The Wacker Neuson is a Genuine OEM Washer sourced directly from Wacker Neuson, ensuring an exact match to the original component installed at the factory. This washer is confirmed to fit a wide range of Wacker Neuson tandem rollers across the RD18-80, RD18-100, RD18-100 C, RD40-130C, and RD45-140C series — including DPF and SE variants — covering multiple production runs and configurations. As a genuine OEM part, it meets the same material and dimensional standards as the part it replaces, so there's no guesswork on fitment or performance.
Key Features
- Genuine OEM Material Consistency — Manufactured to Wacker Neuson's original material grade and thickness specification, ensuring the washer seats, distributes load, and resists deformation exactly as intended for this application.
- Drop-In Replacement — Part number 5100011657 matches the original mounting position and bearing surface dimensions, allowing straightforward installation without adjustment or rework.
- Broad Series Coverage — Fits the RD18-80, RD18-100, RD18-100 C, RD40-130C, and RD45-140C tandem roller families, including US, SE, DPF, and .3 variants across multiple serial ranges.
- Proper Load Distribution — A correctly installed washer prevents fastener pull-through, protects mating surfaces, and maintains correct clamping force. A worn or incorrect washer can lead to fastener loosening, surface damage, and component misalignment during compaction operation.
A washer acts as a load-spreading interface between a fastener and the surface it clamps against. By distributing the clamping force over a wider area, it protects softer or more vulnerable mating surfaces from being damaged by the head of a bolt or nut under torque. On compact and tandem rollers like the Wacker Neuson RD series, washers are used throughout the machine in drive, frame, and vibration system assemblies where consistent fastener tension is critical. When a washer wears thin, deforms, or is missing entirely, fasteners can work loose under the vibration loads inherent to compaction equipment, leading to accelerated wear or component failure.
